5 Axle Rear Dump Semi Trailer with 3 Lift Axles | LUYI Vehicle

High-volume bulk logistics requires maximum legal gross vehicle weight distribution under full load without penalizing fleet fuel economy during unladen return trips. Measuring 11.6m long, 2.55m wide, and 3.8m high with a 1.6m cargo box depth, this 5-axle rear-dump semi-trailer is engineered for high-density bulk cargo, including ores, gravel, coal, and industrial aggregates. Spreading payload across five dedicated axles complies with stringent axle-load regulations while unlocking superior per-trip payload efficiency.

The intelligent full air suspension with multi-axle lift capability provides unprecedented fleet versatility. Through an integrated automated pneumatic lifting control system, the 1st, 2nd, and 5th axles raise smoothly when the trailer is empty. This reduces road contact to just two central running axles, slashing highway rolling resistance, minimizing tread scrub, and reducing tire maintenance costs over long haul routes. Under full load conditions, all five axles deploy instantly to deliver optimal weight distribution, smooth shock absorption, and enhanced road handling.

Outfitted with 385/65R22.5 wide-base super single tires, the trailer significantly sheds tare weight compared to dual-tire configurations while providing low rolling resistance and stable braking response. A front-mounted heavy-duty multi-stage hydraulic telescopic cylinder delivers rapid, stable body elevation for clean cargo discharge, while the automated top tarp system deploys seamlessly to prevent cargo spillage, dust emissions, and moisture contamination during transit.

As a specialized tipper semi trailer manufacturer running our own advanced China dump trailer production line, the high-strength steel U-shaped box, pneumatic lift linkages, and chassis frame are engineered and fabricated in-house at LUYI Vehicle. Ordering factory direct gives fleet operators direct engineering support for box thickness, cylinder specifications, automated tarp types, and axle spacing tailored to regional weight formulas.
